M ETALLIC SHINGLE.

SPECIFICATION forming part of Letters Patent No. 588,161, dated August 17, 1897.

Application filed January 30, 1896. Serial No. 577,393. (No model.)

To aZZ whom it may concern- Be it known that I, LEVI H. Monrnoss, of the city and county of Camden and State of New Jersey, have invented an Improvement in Metallic Shingles, of which the following is a specification.

Myinvention has reference to metallic shingles; and it consists of certain improvements fully set forth in the following specification and shown in the accompanying drawings, which form a part thereof.

Heretofore metallic shingles of ogee type have been employed, but the longitudinal or upright joint between two adjacent shingles came at the lowest place and thus under certain conditions of wind and rain there was a weakness liable not to prevent the beating up of the water to form a leak. My present improvement is to overcome this defect and otherwise improve the construction of this class of shingles. V

In carrying out my invention I so bend or shape the sheet of metal that the joint between two shingles arranged side by side is formed part way up on the side of the same cylindrical or outwardly-projecting curved portion of the shingle, whereby the said joint shall be at a considerable distance from the lowest part thereof. In this manner there is no part of the shingle where the rain might tend to beat up that would be unprotected by transverse ribs, since there are no lateral joints at the lowermost parts in the curve of the shingle.

This improvement depends upon changing the position of the joint in the curved surface of the shingle, and also upon curving the edge adjacent to the lowermost portion upward, so as to prevent the abnormal flow of the rainwater.

My improvement will be better understood by reference to the drawings, in which Figure l is a perspective view of my improved shingle. Fig. 2 is a transverse section of two of my improved shingles, on the line 00 m of Fig. 4, adjusted in position or interlocked; and Fig. 3 is a longitudinal section through two of my improved shingles, showing how they overlap, on the line y y of Fig. 4. Fig. 4 is a plan view.

A is the semicylindrical or outwardlycurved portion, and meets the lowermost or flat portion B in a more or less abrupt bend C. The lateral free edge of the portion B is bent or curved upward, as at D, so as to be considerably higher than the lowermost part of B. The opposite or free edge E of the part A curves downward and outward and is formed with a locking-groove F, arranged at some distance from the bottom and opening downward. The forward edge of the shingle is made with a flange G, and the rear or opposite end is provided with one or more transverse ribs H, preferably two in number and arranged close to the rear edge. These ribs do not extend quite to the lateral edges, so as not to interfere with the interlocking of the adjacent shingles.

It will be seen that when two shingles are interlocked, as in Fig. 2, the lowest part of the shingle is at the bend G and where there is no joint nor interruption of the ribs. Furthermore, it will be observed that the free edge D of one shingle is inserted and forced up into the groove F of the next adjacent shingle and forms a joint at a considerable distance above the lowermost portion of the shingle. This will insure the part B acting as a trough to properly shed the water. The edge E is curved outward, so as to rest upon the roof-boards, and adapted to be secured thereto by nails 1. The flange G of the next shingle to the rear overlaps the rear end of the forward shingle and preferably in front of both ribs H, as shown in Fig. 3. From this it will be perceived that the upwardly-extending edge D prevents lateral entrance of water and the ribs H at the lowermost portion of the body of the shingle prevents the rearward-entrance of water under the beating action of the wind, thus making the roof formed of such shingles peculiarly proof against leakage.

While I prefer the construction shown I do not confine myself to the exact curvatures, as these may be modified without departing from the spirit of my invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The herein-described article of manufacture consisting of an ogee shingle of metal having a semicylindrical and outwardlycurved portion provided with a lockinggroove upon its side near the free edge and considerstituting the parts A and B, and in which the part A is provided with the locking-groove F at a distance above its lower edge, and the part B provided with its free edge D curved upward, and in which further the forward edge of the shingle is provided with the flange G, and the rear edge with one or more transverse ribs H extending up the curved edge D to a considerable distance above the bottom or lowest part of the shingle.

3. An ogee shingle consisting of a sheet of metal having one lateral part bent upward to form a semicylindrical part provided with a foot or edge for attachment to the roof and a locking groove at a considerable distance above the foot, and having the other lateral edge curved upward to a distance corresponding to the distance between the foot and groove and terminating in a free edge to extend into and lock with the groove on an adjacent shingle, and a transverse rib near its upper edge extending along the lowest portion-of the body and upwardly upon both lateral edges.

In testimony of which invention I hereunto set my hand.
